TeamThe Merchant Growth Tribe’s mission is to build an ecosystem of simple yet powerful products for our 1.5m+ merchants around the world which will help them grow their business. In addition to our core product, the Point-of-Sale (POS) application, the teams within the Tribe also provide merchants with invoicing and eCommerce solutions.

Beyond this, we aim to expand SumUp’s ecosystem with additional products and services such as accounting, marketing, loyalty and business analytics, all available in one place. The products we develop strengthen SumUp’s value proposition and ability to serve small merchants around the world.
